Mark Cuban assumes you and the seller are the only people in the market. If there are lots of traders, then the trade price is set by some average assessment of the stock value. Cuban also assumes that you want to buy the stock because you think it's undervalued, and the seller because he thinks its overvalued. But maybe the seller just needs cash, or you just want to invest.
A paradox of economic equilibrium theory is you shouldn't have to do any research: the "invisible hand" of free market should guide all prices to their correct value. The paradox is the theory assumes everyone is fully informed and rational, which seems to conflict with the ability to avoid doing any research. The reality is a more complicated and nuanced picture, which is why I'm surprised how forcefully some people defend free market fundamentalism.
Here's my pet idea: the primary cognitive bias affecting this blog's community lies in underestimating the limits to reductionist explanation.
This is how you end up with statements like "X is not about Y (X is about Z)" even when X is pretty clearly more about Y than about Z (although the world in general may tend to downplay the extent to which X is about Z).
"For every stock you buy, there is someone selling you that stock. What is it that you know that they don't? What is it that they know, that you don't? Who has the edge? If it's not you, chances are you are going to lose money on the deal."
-- Mark Cuban
"If you have two choices, choose the harder. If you're trying to decide whether to go out running or sit home and watch TV, go running. Probably the reason this trick works so well is that when you have two choices and one is harder, the only reason you're even considering the other is laziness. You know in the back of your mind what's the right thing to do, and this trick merely forces you to acknowledge it."
-- Paul Graham
"Never attribute to malice that which can be adequately explained by stupidity."
-- Hanlon's Razor
"I divide my officers into four classes; the clever, the lazy, the industrious, and the stupid. Each officer possesses at least two of these qualities. Those who are clever and industrious are fitted for the highest staff appointments. Use can be made of those who are stupid and lazy. The man who is clever and lazy however is for the very highest command; he has the temperament and nerves to deal with all situations. But whoever is stupid and industrious is a menace and must be removed immediately!"
-- General Kurt von Hammerstein-Equord
"There's no such thing as a human who doesn't commit sin. It's not like the world is divided into sinners and the innocent. There are only people who can and who cannot atone for their sins."
-- Ciel
"Simple stupidity is never enough. People need to pile stupidity on stupidity on stupidity."
-- Mark C. Chu-Carroll
